摘要

冬小麦是黄淮海地区的主要农作物。精确模拟冬小麦产量能够帮助生产者获得更好的经济效益。根据实验资料调整了ALMANAC作物生长模型部分参数后,用其对该地区的冬小麦生长进行了模拟,结果显示ALMANAC模型能够较好地模拟冬小麦的叶面积指数和产量。叶面积指数的模拟结果与实测结果的比值为1.0552,可决系数R2为0.7021;生物量模拟的最大误差为-6.01%,经济产量模拟的最大误差为-5.41%。模型还可以揭示影响冬小麦生长的主要胁迫因素。

Abstract

Winter wheat is the main crop in Huang-Huai-Hai region.Producers can benefit from accurate simulation of winter wheat.Based on experimental data,we adjusted several param eters of ALMANAC crop growth model,and simulated the growth of winter wheat.The result shows that ALMANAC crop growth model can accurately simulate leaf area index(LAI )and the yield of winter wheat.The average ratio of simulated LAI and measured LAI is1.0552,and R 2 is0.7021,the maximum error of simulated biomass is-6.01%,and maximum error of simulated yield is-5.41%,the model can also reveal the reason s that affect the growth of winter wheat.

Key words： crop growth model; winter wheat; simulation; ALMANAC model
